The barb is made of nickel-plated CNC machined brass and the ring is made of anodized CNC machined aluminium. Fittings feature quality rubber O-rings. These fittings are fully compatible with EK-AF series (45°/90°) angled adapters.

These fittings sport low-profile design hence it is mandatory to secure the fitting barb using Allen Key 9mm (not included, available for separate purchase) to prevent skin damage to the finger tips - barb has no finger grip surface.
